Global Ecosystem Dynamics Investigation lidar
2014-09-08 11:37:53

Elizabeth Zubritsky, NASA's Goddard Space Flight Center A laser-based instrument being developed for the International Space Station will provide a unique 3-D view of Earth’s forests, helping to fill in missing information about their role in the carbon cycle. Called the Global Ecosystem Dynamics Investigation (GEDI) lidar, the instrument will be the first to systematically probe the depths of the forests from space. The system is one of two instrument proposals recently selected for...

Researchers Show Evidence Of Common Mineral Capable Of Making, Breaking Bonds
2014-07-30 03:37:00

Arizona State University ASU team shows evidence for one mineral affecting the most fundamental process in organic chemistry: Carbon-hydrogen bond breaking and making Reactions among minerals and organic compounds in hydrothermal environments are critical components of the Earth's deep carbon cycle, they provide energy for the deep biosphere, and may have implications for the origins of life. However, very little is known about how minerals influence organic reactions. A team of...

Carol Rasmussen, NASA Earth Science News Team NASA's Orbiting Carbon Observatory-2, which launched on July 2, will soon be providing about 100,000 high-quality measurements each day of carbon dioxide concentrations from around the globe. Atmospheric scientists are excited about that. But to understand the processes that control the amount of the greenhouse gas in the atmosphere, they need to know more than just where carbon dioxide is now. They need to know where it has been. It takes more...

Brett Smith for redOrbit.com - Your Universe Online UPDATE: July 1, 2014, 5:15 AM From NASA: Today's scheduled launch of NASA’s Orbiting Carbon Observatory-2 (OCO-2) from Vandenberg Air Force Base in California was scrubbed because of a failure in the launch pad water flow. ORIGINAL Several years after the failure of its first mission, NASA will launch the Orbiting Carbon Observatory-2 (OCO-2), which is intended to focus exclusively on studying atmospheric carbon dioxide. The...

NASA NASA’s first spacecraft dedicated to measuring carbon dioxide levels in Earth’s atmosphere is in final preparations for a July 1 launch from Vandenberg Air Force Base, California. [ Watch the Video: OCO-2: NASA’s Carbon Counter ] The Orbiting Carbon Observatory-2 (OCO-2) mission will provide a more complete, global picture of the human and natural sources of carbon dioxide, as well as their “sinks,” the natural ocean and land processes by which carbon dioxide is pulled...

Porous Material Polymerizes Carbon Dioxide At Natural Gas Wellheads
2014-06-04 03:47:25

By Mike Williams, Rice University Rice University scientists have created an Earth-friendly way to separate carbon dioxide from natural gas at wellheads. A porous material invented by the Rice lab of chemist James Tour sequesters carbon dioxide, a greenhouse gas, at ambient temperature with pressure provided by the wellhead and lets it go once the pressure is released. The material shows promise to replace more costly and energy-intensive processes. Results from the research appear...

Decomposing Logs Show Local Factors Play A Greater Role Than Climate
2014-06-03 15:34:25

By Kevin Dennehy, Yale University A new Yale-led study challenges the long-held assumption that climate is the primary driver of how quickly organic matter decomposes in different regions, a key piece of information used in formulating climate models. In a long-term analysis conducted across several sites in the eastern United States, a team of researchers found that local factors — from levels of fungal colonization to the specific physical locations of the wood — play a far...

explaining the Last Glacial Maximum

redOrbit Staff & Wire Reports - Your Universe Online A team of MIT scientists has turned to the Southern Ocean in search of an explanation for the Last Glacial Maximum (LGM), a period in the Earth's climate history during which the northern continents were covered by ice sheets, according to new research appearing in the Proceedings of the National Academy of Sciences. Plankton fossils in deep-sea sediments contain chemical traces that reveal rearranged ocean water masses, as well...
